Part of the CI series, this hex socket drive fastener is machined from steel for consistent clamping force and thread integrity under the repeated loading and vibration common in grooving and parting operations. At 20 millimeters in overall length and 0.13 pounds, it is a direct-fit replacement hardware component for machinists and toolroom technicians maintaining indexable tooling systems on CNC lathes and turning centers.\u003c\/p\u003e\n\u003cp\u003eThis clamping screw is used in production machining environments where GD-style grooving toolholders and cutoff tool blocks require periodic insert changes. It is appropriate for both job shop and high-volume turning operations. Technicians replacing worn or damaged clamping hardware during insert indexing will find this screw matches the standard M6 thread specification required by the toolholder system. Sold individually, it suits spot replacements without the need to purchase a full hardware kit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM6 thread size for direct fitment in GD-style grooving toolholders\u003c\/li\u003e\n  \u003cli\u003eHex socket drive for precise torque application with standard Allen keys\u003c\/li\u003e\n  \u003cli\u003eSteel construction resists deformation under clamping load\u003c\/li\u003e\n  \u003cli\u003e20 millimeter overall length suits standard cutoff tool block geometry\u003c\/li\u003e\n  \u003cli\u003eCI series designation for straightforward cross-reference and reorder\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit — order exact quantities needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with GD-style indexable grooving toolholders and cutoff tool blocks requiring an M6 hex socket clamping screw.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eClamping screw replacement is performed by toolroom technicians or machinists during routine insert indexing. Ensure the machine spindle is stopped and the toolholder is secured in a vise or fixture before removing the existing screw. Use a properly sized hex key to drive the M6 fastener and avoid overtightening, which can strip threads or crack the insert. Inspect the toolholder seat and clamp pocket for debris before installing the new screw.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScrew Type\u003c\/strong\u003e: Clamping Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 20 millimeters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style Compatibility\u003c\/strong\u003e: GD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardware Compatibility\u003c\/strong\u003e: Cutoff Tool Block\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndexable Tool Type\u003c\/strong\u003e: Grooving Toolholder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161500\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 40279770\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728997122354,"sku":"40279770","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c52f417c90cf163173aa8819ff86b0e1.jpg?v=1788698606","url":"https:\/\/voomisupply.com\/products\/accupro-40279770-clamping-screw-m6-grooving-toolholder","provider":"Voomi Supply","version":"1.0","type":"link"}
